Description
Technical field
The present invention relates to having the pipe insulation device of the end cover layer of pressing structure, and relate more specifically to pipeline
Heat ray filter, it includes the end cover layer of pressing structure, and can be in the end cover layer for pipe insulation device
Simplified flowsheet in manufacture process, and rigidity and precision can be improved.
Background technology
Generally, install for transmitting high temperature and high pressure in power plant (such as nuclear power plant and hot power plant), petrochemical plant etc.
The pipeline of steam.As time goes on, these pipelines are corroded due to high temperature and high pressure steam, thus duct wall is thinning.
As time goes on, the thinning of this duct wall can make to produce aperture in pipeline, leads to serious accident.For
This reason, carries out once calculated maintenance every year, thus carries out the thinning inspection of wall on pipeline, and records and report inspection
The result looked into.
In the case of carrying out the thinning inspection of this wall, if existing insulator has been applied on pipeline, with
Remove end metal cladding and the insulator outside pipeline afterwards, then carry out the thinning inspection of wall.Carrying out the thinning inspection of wall
After looking into, adhere to new insulator, then carry out terminating processing using end cover layer.
Apply the mode of insulator after this inspection thinning in wall, substantial amounts of waste, such as insulator and knot can be caused
Bundle cover layer, it leads to a large amount of wastes of material.Especially, in the case of application insulator on elbow or T connector portion, phase
Need higher technology than in the situation that insulator is applied on straight tube, and if mistakenly applying insulator, then can be formed
Hot breach, thus can increase thermal stress, and the wall of appropriate section is thinning significantly to be carried out, thus, the life-span of whole plumbing installation
May reduce.
Solution to this problem proposes (to be registered in September 13 in 2012 in Korean patent No. 10-1184392
Day).In Korean patent No. 10-1184392 (be registered in 2012 on September 13), pipe insulation device includes the heat-insulated list of elbow
Unit, T connector insulating unit, straight tube insulating unit and flange insulating unit, and each insulating unit includes two or more
Section, and each section is made up of multiple thermal insulation layers, and is coated with end metal cladding.
